What 2020 Audi A6 Allroad owners say
Electrical system
My electrical system failed and the car died on the freeway. This is now recognized as a chronic problem- a software bug in the 48 volt mild hybrid system- with several Audi models, including this A6 Allroad. The bug apparently damages the vehicles alternator, which must then be replaced. There is a several month backorder on this part, so hundreds if not thousands Audis remain unrepaired on the lots. They are dying on roads across the USA on a daily basis.
While driving I received two messages to contract service first that the "electrical system malfunction" and then a "starting malfunction" which was fallowed by a battery light and a check engine light. I contacted my local dealer they advised I have it towed in immediately. The car was towed in and it's a "starter generator" and is back ordered with no eta. The car is not drivable and is at the dealer for an unknown amount of time.
